Ground source heat pumps present a relatively affordable and eco friendly way to use spare heat from the earth for heating and cooling both residential and industrial structures. Initial set-up expenses can be quite a lot higher than traditional air-source systems, but geothermal heat pumps provide considerably lessen ownership costs over the long term. Ground source heat pumps (GSHPs) are units that use the earth?s temperature to supply heating, cooling and hot water for commercial companies and housing establishments. The systems are fashioned to take advantage of the fact that temperatures remain at a close to constant level of amongst 7 C and 21 C just a few feet underneath the ground, regardless of geographic area or surface air temperatures. Through winter, the units essentially draw out heat from the ground and shift it to a commercial building or house, whilst in summer the systems draw out heat from building interiors and transport it to the ground. Ground source heat pumps are electrically driven and are sometimes referred to as geothermal heat pumps, or geo-exchange pumps, or merely as earth-coupled heat pumps. A full-fledged GSHP machine is composed of a heat pump, a ground loop system for absorbing heat from the ground or rejecting it back to the ground, and air ducts or radiant floor systems for providing the hot or cold air. The ground loop system typically is made up of many loops of plastic tubing filled up with antifreeze liquid or water, buried under the ground in horizontal or vertical style. Through winter, the liquid in the loops collects heat from the ground and pushes it to the heat pump where a compressor elevates the temperature even more before circulating it through the building. The flow of the liquid inside the loops is reversed throughout summer. This results in the warmer air being taken out from the building and moved to the ground while cooler liquid is circulated back to the heat pump and then throughout the building. An open loop system works in more or less the same style, but in this instance the liquid in the loops is usually ejected into the earth. Ground source heat pumps have been utilised since the 1940s and are considered a more environmentally-friendly and cost-effective substitute to regular air-transfer based heating and cooling systems. Research have demonstrated that GSHP systems have heating efficiencies up to 70% higher than conventional systems and cooling efficiencies of nearly 40% above than air-conditioners. The primary cost of setting up a geothermal heat pump can be quite high compared to traditional heating and cooling systems. However, over the long term the pumps are less costly to own and to manage. They also can deliver up to 50% savings on energy use. In some cases, a geothermal heat pump is installed along with an air-source heat pump as a way to lower initial installation costs. Discover more facts about Ground Source Heat Pumps
